DateTime::DateTime(DateTimeInitSystem) had initialized Date and Time separately, which causes a slight possibility that it could get a wrong datetime with almost 24 hours delay when it went beyond midnight. E.g., the date part was of the previous day while the time part was 00:00:00.xxx of the next day. This also reduces duplicate code by sharing GetSystemDateTime().
